WATC H CHAIN.

SPECIFICATION forming part of Letters Patent No. 263,691, datedSeptember 5, 1882.

7 Application filed March 13, 1882. (No model.)

To all whom it may concern Be it known that I, WILLIAM 0. EDGE, ofNewark, county of Essex, and State of New Jersey, have invented a newImprovement in \Vatchllhains, of which the following is a specification.

Figure 1 represents a front elevation of a machine for shaping thewatch-chain according to my invention. Fig. 2 is a face view of amodification ot' the rollers. Fig. 3 shows an ordinary fox-tail chain.Figs. 4 and 5 are side views of my improved watch-chain. Fig. 6is anend'view of the same. Fig. 7 is a perspec. tive view of a link of thechain shown in Fig. 3, and Fig. 8 a perspective view of the link of myimproved chain which is shown in Figs. 4

. and 5.

This invention has for its object to make out of an ordinary fox-tailchain a fiat chain having a projecting rib on each side. A fox-tailchain is one made out of U-shaped links.

Each link is first straight and pushed through endeavor is to produce achain composed solely of such links, which chain shall have ribs on thefaces, as indicated at a a, in Figs. 4,, 5, and g, and which chain shallotherwise be quite at. I

To this end I take the ordinary fox-tail shown in Fig. 3, which iscomposed of links like that shown in Fig. 7, and introduce it betweenthe grooved rollers A and B, (see' Fig. 1,) which will compress thefox-tail chain, but leave a projecting rib on each face; or there may bemore than one groove in each of the rollers, as in Fig. 2, in which casethere will be more than one projecting rib on each face.

[ The resultof the pressure on each link will be to transform it fromthe outline shown in Fig. 7 to that shown in Fig. 8--nan1ely, to pressits ends flat together and render them practically flat, and to bend outits middle portion to form there the projecting bulges b, which in thecompleted chain produce the ribs a, said ribs being made up ofdiagonally-placed sections of links.

I am well aware that it is not new to shape a continuous bar so as toleave a rib or ribs on its face orfaces by passing it through rollerssuch as are shown in Figs. 1 and 2, and I do not claim anythingin theprocess of treating known substances bysuch rollers; but, to myknowledge, a flexibly-jointed chain for ornamental or other purpose hasnever been produced out of links flat and with projecting ribs. Such aflat chain, when produced in accordance with the foregoingspecification, is very flexible, is much more easily cleaned than theordinary fox-tail chain, which has deep recesses or grooves in its facesin which the dirt will set-tleto such an extent as to render thecleaningof the chain practically impossible; but when the fox-tail chainhas been pressed according to my invention all recesses disappear, andthe rounded wire links present fiattened faces on the outside, and inevery respect the appearance and the utility of the chain are thusincreased.

I claim- A chain composed solely of links that have bulging-out portionsb b, said chain being flat throughout, with the exception of projectingribs or a on its face, substantially as herein shown and described.
